HighlightsPrimary ovarian leiomyoma is one of the rarest solid tumours of the ovary.Many patients with ovarian leiomyomas are nulligravidas.Differential diagnosis can be difficult from ovarian solid tumours.The diffuse strong positive staining for SMA is characteristic of leiomyoma.Unilateral and benign tumours can be treated with unilateral salpingo-oopherectomy.

BackgroundThe Milan system reporting salivary gland cytopathology (MSRSGC) is a tiered classification scheme that is based on risk stratification. The aim of the current study was to assess the risk of malignancy (ROM) and risk of neoplasia (RON) in each of the diagnostic categories proposed by the MSRSGC.MethodsA retrospective analysis and categorization according to the MSRSGC was made of salivary gland fine needle aspirations (FNA) performed from January 2007 to December 2017. The FNA cytology results were correlated with subsequent histological follow‐up.ResultsA total of 578 FNAs were evaluated and histopathology was available for 198 cases (34.2%). The RON and ROM for individual diagnostic categories were: Non‐diagnostic: 52.2% to 13%, non‐neoplastic: 21.4% to 10.7%, atypia of undetermined significance: 74% to 22.2%, benign neoplasm: 100% to 1.1%, salivary gland neoplasm of uncertain malignant potential: 93.3% to 53.3%, suspicious for malignancy (SFM): 100% to 100%, and malignant: 100% to 100%. A diagnosis of 'SFM' or 'malignant' with FNA cytology carried a 100% risk for malignancy, while a diagnosis of “non‐neoplastic,” “benign neoplasm” reduced the probability of malignancy to 3.4%.ConclusionThe MSRSGC is useful for the management of salivary gland lesions as it can successfully differentiate between benign and malignant cases. It will bring uniformity in salivary gland FNA cytology reporting across various institutions globally.

Hydatid disease is a parasitic infection that most commonly affects the liver and lungs, although the disease can arise in any part of the body. Cysts may mimic many benign and malignant conditions. The diagnosis cannot be confirmed preoperatively in all cases. A 44-yr-old menopausal woman was admitted to the department of gynecology with complaints of abdominal distention. A fixed abdominopelvic mass was identified. Radiology revealed a 20-cm mass with branched septations and solid components. CA-125 level was 55 kU/L, and Risk of Malignancy Index-2 score was 880. These findings suggested the presence of an ovarian neoplasm, and laparotomy was performed. Cystic masses measuring 22 cm and 4 cm, originating from the omentum majus and left ovary, respectively, were found during surgery. Frozen-section analysis revealed hydatid disease. Infracolic omentectomy and total abdominal hysterectomy with bilateral salpingo-oopherectomy were performed. Results of a serum Echinococcus hemagglutination test performed immediately after surgery were negative. The patient was prescribed albendazole for 6 mo and discharged on the third postoperative day with no complaints. The incidence of hydatid disease in the female reproductive system is very rare; however, clinicians must be aware of this disease and take necessary precautions while operating because any spillage may lead to anaphylactic shock and increased risk of recurrence.

We present a 48-year-old male patient with a mass in the tail of the pancreas on abdominal ultrasonography. The lesion was suspicious for a well-differentiated pancreatic neuroendocrine tumor and spleen preserved distal pancreatectomy surgery was performed. It was diagnosed as intrapancreatic accessory spleen (IPAS) after pathological examination. Accessory spleen is not an infrequent congenital entity caused by the localization of normal splenic tissue in ectopic regions. As it is known, an accessory spleen is a benign entity and does not require surgical treatment or follow-up when detected. However, it is important to recognize IPAS tissue as it may mimic a pancreatic neoplasia when it is located in the pancreas. In this article, we discuss the differential diagnostic possibilities of the IPAS entity.
